blank window when displaying movies through video-projector


Hi,

I need to display some movies in a presentation using a video-projector connected to my laptop. The problem is that the movie is well displayed on the laptop screen, but I get a uniformly blue window on the screen projected (while the rest of the presentation is displayed correctly. Only movies (avi, DVD...) are badly displayed). I get the same result using either mplayer or xine. Note that the result is the same if the movie is displayed in a window or in fullscreen.
I also tried with my desktop monitor and got the same effect.

If this might help you to figure out what the problem is (and perhaps you have a solution :-), I have a Dell inspiron 4100, with a Nvidia Geforce2 Go video card, and I'm running Mandrake 9.0.

Thank you very much by advance for any help!
Guillaume

easy fix

I had the same problem; doing the following (from thinkwiki.org -- search for Additional_options_for_the_radeon_driver ) worked for me on my Thinkpad T42:

Add this line:
Option "MonitorLayout" "LVDS,NONE"
to the Device section in your /etc/X11/xorg.conf

to quote:

> First of all, suppose you want to plug in your laptop into a
> projector occasionally, but you don't want to restart X when you do
> so. The easiest thing is to not use any of the CRT2 options and use
>
> Option "MonitorLayout" "LVDS,NONE"
>
> The vga port will carry the same signal as the laptop display (at
> least on my T42p). If the projector does not support the
> resolution, you can change it using xrandr.
